I would like to ask what can the local bmw dealership/service retrofit onto the Bmw X3. I heard stuff like the rear view camera and navigation can be retrofitted at the bmw dealeship/service. Is this true? And also where could I buy new black leather seats front and back.

The car is a late 2012 europe spec X3 20d

Whatever is available will be specific to geography. What is available in one area might not be available in another area (e.g rear view camera: I saw a post it was available in some parts of Europe but not available in the U.S.).
